HEEL-B UlLDlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 752,325, dated February 16, 1904.

Application filed November 15, 1902. Serial No. 131,514. (No model.)

To all whom it may concern.-

Be it known that we, WENDELL P. Boswonrn and THOMAS BosrocK, of Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Heel-Building Machines, of which the following is a specification.

This invention relates to heel-nailing machines, and more particularly those in which the heel is built up with a series of lifts which may be composed of separate pieces. 7

The invention has for its object to simplify the machine and save time in the operation of assembling the nails'and the heel.

The invention consists in certain novel features of construction and arrangement hereinafter described and claimed.

Of the accompanying drawings, Figure 1 represents a vertical sectional view taken longitudinally through the slide which carries the nail-assembling templet and the mold. Fig. 2 represents a section on line 2 2 of Fig. 1. Fig. 3 represents a sectional view of -the mold and adjacent parts with a heel under pressure. Fig. 4.represents a section on line v 4 4 of Fig. 2. Fig. 5 represents a longitudinal vertical section showing the nail-assembling templet in register with the nail-receiving templet. Fig. 6 represents a-similar view showing the mold in register with the nailreceiving templet. Fig. 7 is an enlarged sectional view on line 7 7 of Fig. 4. Fig. 8 represents a section on line 8 8 of Fig. 1.

. The same reference characters indicate the same parts in all the figures.

In the drawings, lO-is a fixed horizontal bed-plate provided with a nail-receiving templet 11, having holes 12 12 in which operate driver-pins 13 13, attached to a Stem 14. To reciprocate the latter vertically, it is shown as formed with rack-teeth 15, engaging a pinion 16, oscillated by a lever 17; but various other methods of operating the driver-pins might be employed.

18 is a slide mounted abovethe bed-plate and having at one end a templet 19 provided with nail-holes 2O 20 corresponding in arrangement to the holes 12 and at the other.

end provided with a heel-assembling mold 21,

composed of sections 22 22, normally pressed apart by springs 23 2-3.

24 is a front stop, and 25 is a finger-ridge, wherebythe operator manually engages the slide 18 to reciprocate it. To temporarily arrest the slide 18 with the holes 20 of the templet 19. in register with the holes 12 of the templet 11, there is provided a stop-bolt 26, normally projected by a spring 27 into the path of the slide 18, but provided with a hand-lever 28 for retracting it from said path. When permitted by the retraction of the stop 26, the slide 18 can be moved to bring the mold 21 into register with the templet 11, and in this position of register the slide is arrested by adjustable stop-screws 29 29, adapted to abut shoulders 30 30 on the slide.

Mounted to reciprocate above the templet 11- and in line therewith is a stem 31, carrying at its lower end a heel-presser 32, which also acts as an anvil to clench the nails. The said stem embodies a lower section 33, held from rotation by a spline-screw 34, and an upper section 35, having a screw-threaded adjustable connection 36 with the lower section. At the upper end of the section is a head 37, abutted by a-cam 38 on a lever39, pivoted upon a pintle 40. Said upper section 35 is normallyheld from rotation by sliding pins 41 41, elevated by springs 42 42 and adapted to singly engage notches 43 43, formed in the head 37. The springs 42 hold the head 37 ment with respect to the stem-section 33,

whereby the pressure exerted by the presser 32 is regulated according to the thickness of the heel. The pintle is mounted in fixed bearings 44 44, and outside of said bearings it carries twin cams 45 45, hearing against vertically-moving slides 46 46, elevated by springs 47 47 At their lower ends the slides 46 carry wedges 48 48, operating against the inclined outer sides of the mold-sections 22, whereby the mold is caused to contract by the descent of the slides 46. The object of the sectional mold is to release a heel having substantially straight or upwardly-taperin g sides.

Below the mold 21 in the outermost position of the slide 18 is an ejector 4:9,, operated by a lever 50. V

In the operation of the machine the nails and heel are assembled, respectively, in the templet 19 and mold 21, while the slide 18 is in its outermost position, (represented in Figs. 1 and 4,) the nails being point uppermost. The slide 18 is then moved inwardly until it encounters the stop 26, whereby the templet 19 is brought into register with the templet 11 and the nails drop from the holes 20 20 into the holes 12 12. The stop 26 is then retracted and the slide 18 pushed in until stopped by the screws 29, the mold 21 being thereby brought into register with the templet 11. The lever 39 is then swung to the right as viewed in Fig. 1 to a substantially horizontal positon, which operation contracts the mold laterally upon the heel by the action of the wedges 48 and exerts vertical pressure on the heel by the action of the presser 32. The driver-pins 13 are then operated by the elevation of the stem 14 to drive the nails through the heel 51 and secure its lifts together. After the heel has been nailed the pressure thereon is relieved by throwing up the lever 39, and the operator withdraws the slide 18 and knocks out the heel by means of the ejector 49.

We claim 1. In a heel-building machine, a nail-receiving templet, nail-driving means operating therethrough, and a nail-carrying templet and 4 a heel assembling mold movable alternately into register with said nail-receiving templet.

2. In a heel-building machine, a nail-receiving templet, nail driving means operating therethrough and having an upward driving stroke, a nail-clenching abutment mounted above said nail-receiving templet, and a slide movable between said templet and abutment and having a nail-carrying templet and a heelassembling mold.

3. In a heel-building machine, anail-receiving templet, nail driving means operating therethrough, a nail-carrying templet and a heel-assembling mold movable alternately into register with said nail-receiving templet, a presser mounted opposite said nailreceiving templet, and means to move said presser toward and away from said nail-receiving templet.

4. In a heel-building machine, a nail-receiving templet, nail-driving means operating therethrough, a reciprocating slide having a nail-carrying templet and operative to move the same into and out of register with said means, said slide having limiting positions on either side of said position of register relating to difierent operations connected with the heel, and provided with means to carry the heel and retractile means to stop said slide in said position of register. ,7

5. In a heel-building machine, a nail-receiving templet, nail-driving means operating therethrough, a slide having a nail-carrying templet and a heel-assembling mold, and operative to position these successively in register with the nail-receiving templet, retractile means to arrest said slide with the nail-carrying templet in register with the nail-receiving templet, and means to stop said slide with the mlold in register with said nail-receiving temp et.

6. In a heel-building machine, nail-driving means and a mold contracting mechanism adapted to operate on the heel in the same position thereof, and a contractile mold mount- .ed for movement into and out of alinement with said nail-driving means, and into and out of cooperative relation with said mold-contracting means.

7. In a heel-building machine, a heel-presser and a mold-contracting mechanism connected for simultaneous operation, and a contractile mold movable laterally into and out of register with said presser and mechanism.

8. In a heel-building machine, a nail-receiving templet, nail -driving means operating therethrough, a heel-presser opposed to said means, a mold-contracting mechanism connected for simultaneous operation with said presser, and a slide movable between said presser and nail-receiving templet and having a nail-carrying templet and a contractile mold, the latter carried by movement of said slide into and out of cooperative relation with said mechanism.

9. In a heel-building machine, a nail-receiving templet, nail-driving means operating therethrough, a heel-ejector,- a slide havinga nail-carrying templet and a heel-assembling mold and having three positions, in the first of which said mold registers with said ejector, in the second of which said templets register with each other, and in the third of which said mold registers with said nail-receiving templet, and devices to arrest said slide in said three positions.
